The present teachings disclose nucleic acid cassettes for expressing in an insect cell a plurality of polypeptides encoded by a gene comprising overlapping open reading frames (ORFs). A cassette comprises, in 5' to 3' order, a) a first insect cell-operabie promoter, b) a 5' portion of a gene comprising a first ORF of the gene, c) an intron comprising a second insect cell-operable promoter, and d) a 3' portion of the gene comprising at least one additional ORF. Vectors and insect cells comprising the cassettes are also disclosed, as well as methods for production of recombinant adeno- associated virus in insect cells using the cassettes. |
